So, does this qualify as an in-line reply, or a top post? Maybe it's a
medium post ;)

If both calls were in the LAN, chances are good that the phones will have
re-invited to go around the SIP server. If that's the case, then it
shouldn't be a problem.

Now, if dial options, recording, or SIP settings prevent reinvites, then
this might be part of the problem.
